Abstract
A moving target detecting system for identifying a moving target by distinguishing the moving target from a background precisely and quickly is disclosed. In the system, an image pick-up unit for picking up images of an objective area including at least an identical region up to two screens or more on a time series basis, a feature value detecting unit for dividing respective images, which have been picked up by the image pick-up unit into plural segments to have substantially identical profiles and then detecting image feature values in connection with brightness information in respective segments from each of the plural segments, and a discriminating unit for discriminating the moving target based on differences in locations between respective segments which can exhibit substantially identical image feature values, by comparing the image feature values in respective segments on one screen out of the screens, from which the image feature values are detected by the feature value detecting unit, with the image feature values in respective segments on another screen on a time series basis provided.
